Population Size

Score3 - Vey Small: Generally <2,000 individuals.

Commentvery few individuals documented.

Range Extent

Score2 - Regional or State Endemic or Small Montana Range: Generally restricted to an area <100,000 sq. miles (equivalent to 2/3 the size of Montana or less) or Montana contributes 50% or more of the species’ range or populations OR limited to 2-3 Sub-basins in Montana.

Area of Occupancy

Environmental Specificity

Score1 - Moderate: Species is restricted to a specific habitat that is more widely distributed or to several restricted habitats and is typically dependent upon relatively unaltered, good-quality habitat (C Values of 5-7).

CommentHabitat does not appear to be unique nor especially rare.

Trends

ScoreNA - Rank factor not assessed.

CommentTrends are unknown.

Threats

Score1 - Medium: 11-30% of the populations are being negatively impacted or are likely to be impacted by one or more activities or agents, which are expected to result in decreased populations and/or habitat quality and/or quantity.

CommentNo specific threat or combination of threats appear to be severe in magnitude or immediacy. Timber harvesting, road maintenance and successional dynamics all have the potential to detrimentally impact the species, though none appear to be significant threats at this time.

Intrinsic Vulnerability

Score0-2 - Vulnerability Unknown.

CommentSpecific life history attributes which may limit the species' viability are undocumented.

Raw Conservation Status Score

Score10 to 12 total points scored out of a possible 16 (Rarity factors and threats only).
